SPECIFICATION forming part of Letters Patent No. 606,509, dated. June .28, 1898.

Application filed July 27, 1897. fierial No. 64.6,ll6. (No inodel.) I

To aZZ whom it may concern:

Be itknown that I, AUGUST BRAATZ, a citizen of the United States, and a residentof WVausau, in the county of Marathon and State of Wisconsin, have invented certain new and useful Improvements in Plow-Clevises; and I do hereby declare that thefollowing is a full, clear, and exact description of the in vention, which will enable others skilled in the art to which it appertains' tomake and use the same, reference being had to the accompanying drawings, which form a part of this specification. My invention relates to improvements in clevises and draft-bars for plows; and its object is to provide an improved construction of the same, whereby I secure important advantages with respect to efficiency in use.

The invention consists in the novel construction and combination of parts hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a perspective view showing my improvements. Fig. 2 is a similar view showing a modified construction. Fig. 3 is a sectional view of the same.

In the said drawings, referring now to Fig. 1, the reference-numeral 1 designates a plowbeam of any suitable construction provided at the front end with lugs 2, with which is connected a vertically-adjustable clevis 3, the lower end of which is provided with a horizontal arm or bar 4, formed in the under side with a number of semicircular recesses 5. Secured to said arm or bar by set-screws 4 is a bar 4 formed with coinciding recesses 4, so that when said plates are connected with each other there will be formed circular holes between them. Passing through one of these holes is a draft-bar 6, having a hook at its front end to engage with a'whiffletree. This bar extends rearwardly and has its rear end formed with a hook 7, which engages with a clip' 8, secured to the plow-beams. The arm 3 is formed with a number of holes 3 through which and the holes in the lugs 2 passes a removable pin 3. By this construction the depth of penetration or cut of the plow can be regulated and the use of a wheel at the front end of the beam is obviated; also by shifting the bar to the right or left the draft can be equalized.

In the modification shown in Figs. 2 and 3 the clevis is provided with a vertical slot 9, through which passes a pin 10. The rear side of said clevis is provided with wormteeth, with which engages a worm-wheel 12, secured to a rotatable shaft 13. By rotating this wheel the clevis can be elevated and lowered. The arm at the lower end of the clevis at each end is provided with a lug 14,

through which passes a rod 15,screw-threaded intermediate to its ends and passing through a screw-threaded aperture in the draft-bar. By turning this rod the draft bar is shifted to the right or left to equalize the draft.

Having thus fully described my invention, what I claim is In a plow, the combinationwith the beam and the lugs at the front endthereof formed with opposite holes, of the vertically-movable arm or bar formed with a number of holes, the pin passing through said holes, the horizontal armor bar at the lower end of said vertically-movable arm or bar formed with recesses in the under side of the bar secured thereto formed with coinciding recesses in its upper side, the set-screws connecting said bars, the rod passing through said recesses formed with a hook at the front end and the clip secured to the beam with whichthe rear end of said rod is connected, substantially as described.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.

' AUGUST BRAATZ.
